HI Sueposer, I did the GIDome that are sell in Daz3D. The ideia for my GIDome is use a simple map to simulate light like a studio light, but using the same idea that a HDRI image can do. And even sky light and others can replace all light sources in the final render. Almost all my images are rendered using it and no light source. Those images are did to use as a more real reference light source and take a little more to render, but get the best results...
